What Is a Computer Mouse?

A mouse is a device that controls the movement of the cursor (pointer) on a computer's display screen.

The plural of the mouse is mice. Some old mice have got two buttons, the right and left buttons while modern ones will have a third scroll button in between the two.

To use the mouse, one must point and click to issue instructions to the computer. It is an important part of the computer as it helps to make our work easy.

Who Invented the Mouse?

It was invented by Douglas Engelbart of Stanford Research Center in 1963 and then pioneered by Xerox in the 1970s. This invention came as a breakthrough in computer ergonomics.

A mouse connector is a dedicated socket or an interface on the computer for connecting a mouse. Since the invention of the first personal computer by IBM back in 1981, different types of mouse connectors have been developed.

Let us have a look at them one at a time.

Types of Computer Mouse Connectors

Here is a list of five different types of computer mouses with comprehensive descriptions.

1. Bus Mouse

The first type of mouse was connected to the PC by the use of a bus. Thus it was actually being referred to as the bus mouse. It was used in the early days of the IBM-compatible personal computers.

It connected to the PC through a specialized bus interface implemented via an ISA add-in card. It was superseded by the serial mouse.

2. Serial Mouse

The serial mouse was connected to the computer via the serial port. A serial port is a physical communication interface. Through this port, information is transferred in and out of the computer bit by bit.

The serial port is a D-type 9 pin male port (DB9M) at the back of the motherboard. Its corresponding connector must then be a female connector for them to mate correctly. The serial mouse is obsolete.

3. PS/2 Mouse

The PS/2 mouse is connected to the PS/2 port (green in colour). The PS/2 mouse connector is a 6-pin mini-din connector designed in 1987.

It superseded the serial connectors. Its name is derived from IBM's personal systems/2 series of personal computers, which were introduced in 1987.

This PS/2 mouse port first featured in these PS/2 systems and continued being used in newer designs. This was even after the PS/2 systems were no longer in production.

The colour code for the PS/2 port for most computers is usually green.

4. USB Mouse

The physical shape and appearance of the USB mouse are similar to the others. The only difference is the connector that connects to a USB port on the back of your PC.

The Universal Serial Bus has replaced the PS/2 ports, though some of the computers still have the PS/2 ports. This industry standard was developed in the mid-1990s.

It defines the cables, connectors and communication protocols for connection and communication between computers and attached peripheral devices.

The USB port also provides power to the attached device hence eliminating the need for power connectors.

It was purely designed to standardize the connection of computer peripherals. These are devices like mice, keyboards, digital cameras, smartphones, PDAs, Video game consoles, removable disk drives, etc.

The USB ports support hot-plugging where you connect or remove a device without turning off your computer. It also supports daisy-chaining where you can connect 127 USB devices in a single port through the use of a USB hub.

5. Wireless Mouse

This is the latest type of mouse that does not use a cable to connect to the back of your computer. It is a neat type of mouse to use because it eliminates the clutter of cables on your desktop.

A good example is the VicTsing MM057 2.4G Wireless Mouse Portable Mobile Optical Mouse. Below are several of the features it has.

  • Comfortable Ergonomic Design: This mouse comes with a streamlined arc and thumb rest to help reduce the stress caused by prolonged use of the. The side pits help reduce slippage and maximize your feeling of use.
  • Save Battery Life: It comes with up to 15 month’s battery life. This solves the problem of changing batteries frequently. This computer optical mouse will be in sleep mode in 8 minutes of inactivity. Press any button to wake it up.
  • Plug and Play: Making it easy to use. There is no need for any drivers. This computer mouse support 33ft wireless connections, you can avoid being bothered by the power cord and use this mouse anytime, anywhere.
  • Multi-Function Wireless Mouse: It comes with 5 levels DPI: 800/1200/1600/2000/2400. This will help you easily change the cursor sensitivity depending on your activity. Two side buttons that you can use to control the page forward/backward for increased productivity. Advanced technology helps the mouse moves around the computer screen smoothly!
  • Wide Compatibility: It is compatible with Windows7/8/10/XP, Vista7/8 and Linux, etc. It is designed for desktop, laptop, PC, Macbook and other devices.
  • Connections: Some of the wireless mouses can connect via a USB receiver while others make use of the Bluetooth connection. The mouse is powered by a pair of batteries, usually AA type.

Questions & Answers

Question: How does a wireless mouse connect to a computer?

Answer: Most wireless mice use radio frequency (RF) technology to send information to your computer. Radio Frequency devices require two main components in order to communicate; a transmitter and a receiver. Here's how the wireless mouse communicates with a computer:

The transmitter is housed in the mouse and it is powered by a battery that will be found on the underside of the mouse compartment. The transmitter sends an electromagnetic (radio) signal that encodes the information about the mouse's movements and the buttons you click.

On the other hand, there is a receiver connected to your computer. It accepts the signal, decodes it and passes it on to the mouse driver software and your computer's operating system.

The receiver, on the other hand, can be a separate device that plugs into your computers' USB port, it can be a special card that you place in an expansion slot or a built-in component.

Hello Daggy, an interface is a link or the way you connect a device to the computer. Some of the mouse interfaces are; Serial interface, PS2 Interface, USB, and the Cordless or wireless

Daggy mkubwa on July 02, 2018:

What are the types of mouse interface...

Are right and left click,drag and droppart of them?kindly enlighten

Patrick Kamau (author) from Nairobi, Kenya on May 27, 2018:

Wow, Peter, that must be a very old PC, a 486 or Pentium processor. Well, keep it running and hope you preserve it well for future generations.

Peter on May 27, 2018:

How dare you say the serial mouse is obsolete, lol. I'm still using one on an older PC that doesn't have USB

Thanks a lot Silwen, for reading and commenting. I came up with this review to help new comers in the IT field. I will definitely check that one of optical mice.

Silwen from Europe on February 08, 2012:

Great review of mouse connectors. It was interesting to read, because I have huge interest in computer engineering. Some time ago I have made a hub about optical mice and how they work. I would appreciate your opinion about that.

Thank you for sharing this information.
